I would like to submit my paper to conference X or journal Y as well as to SIGGRAPH Asia 2009.
You must submit to just SIGGRAPH Asia 2009 and await our response before submitting elsewhere (should your work not be accepted by SIGGRAPH Asia 2009). You will have a chance to see the reviews and scores during the rebuttal period starting on 14 July, 2009, and may withdraw your paper at that time (or at any other time) if you choose to do so. If you submit your paper to another conference or journal simultaneously, we will reject your paper without review. We'll be in contact with the editors of several graphics journals, and chairs of other graphics-related conferences, swapping information. Several double submissions to SIGGRAPH have been found in recent years.

I would like to submit my paper to conference X. Their submission deadline is after SIGGRAPH Asia 2009's program committee meeting, but they require abstracts to be submitted before SIGGRAPH Asia 2009's program committee meeting. May I submit the abstract?
Yes. The prohibition against dual submission kicks in when a full paper substantially equivalent to your SIGGRAPH Asia 2009 paper is submitted elsewhere. For conferences that require extended abstracts or other formats, you should ask the Papers Chair before submitting, to avoid risking your paper being rejected from SIGGRAPH Asia 2009.

But I want my paper to be in SIGGRAPH Asia 2009. I promise that if it's accepted by SIGGRAPH Asia 2009, I'll withdraw it from the other conference or journal.
We appreciate your eagerness to have your paper published by SIGGRAPH Asia 2009. There is only one route to having this happen (see the previous paragraphs).

We've submitted a paper about a pilot study to conference X, and now we'd like to submit a paper about the full-blown user study to SIGGRAPH Asia 2009. How should we go about that to avoid the perception that it is a dual submission?
Cite the submitted paper in your SIGGRAPH Asia 2009 submission with a note to the reviewers that either it will be accepted by conference X, or you will publish it as a tech report and make it freely available on the web. Send in an anonymous version with your SIGGRAPH Asia 2009 submission. Then when you write the SIGGRAPH Asia 2009 paper, treat the pilot study as already published. Don't repeat text or figures from that paper in the SIGGRAPH Asia 2009 version.

I sent in a paper to workshop X with the understanding that it was for review purposes only, and the workshop would have no published proceedings. Now, four months later, they tell me that they're going to publish the proceedings and include it in the digital library. Unfortunately there is significant overlap between that paper and my submitted SIGGRAPH Asia 2009 paper. How should I handle this?
We realize that you didn't intend to do anything against the SIGGRAPH rules, but now that the workshop rules have changed, you should either withdraw the workshop paper from the proceedings or withdraw your SIGGRAPH Asia 2009 submission.

Prior Publication

I am thinking about submitting a paper to SIGGRAPH Asia 2009, and I'm uncertain about the requirements. Specifically: "Your paper cannot have been previously published in an equivalent or similar form. A paper is considered published if it has appeared in a peer-reviewed journal or in published meeting proceedings that are commercially available afterward to non-attendees, regardless of the language of that publication." Does this include abstract-reviewed published meeting proceedings (for example, SPIE proceedings)? Does your restriction apply to papers accepted for journal publication?
If the meeting proceedings are published in a form that is visibly, reliably, and permanently available afterward in print or electronic format to non-attendees (as in the case of SPIE proceedings), then it is not appropriate to submit a paper that has been so published to SIGGRAPH Asia 2009. If your work has been accepted for journal publication (or even submitted), it is not appropriate for submission to SIGGRAPH Asia 2009. For more details, see Prior Art & Public Disclosure.

How do I reference an ACM SIGGRAPH Sketch on the same topic as the paper that I am writing?
Depending on the year of presentation, the Sketch might appear in the ACM Digital Library. If it does, you should use the ACM Digital Library as a reference. If it is not archived, you may refer to the oral presentation at the conference or the abstract, if it appeared in one of the conference publications. If you were the author of a Sketch whose full text is no longer available to the public, then citation is not strictly necessarily because presentation of a Sketch does not preclude publication of a full paper. If you were not the author of the Sketch, then you should cite the Sketch to respect the author's ideas. If the authors have published a subsequent paper, thesis, or tech report about their work, you should cite that instead of the Sketch because it will be a more useful pointer for your readers.

A month after submitting our paper, we obtained much better results. Can we withdraw our paper from review and submit it elsewhere (or wait until next year)?
SIGGRAPH Asia 2009 submissions can be withdrawn at any time. However, authors should remember that the program chair and the senior reviewers on their paper know who they are, and may have already spent considerable effort reviewing their paper. Withdrawing a paper won't help your reputation with these reviewers. You will have a chance to see the reviews and scores during the rebuttal period starting on 14 July, 2009, and if you withdraw your paper at that time to submit it elsewhere, the reviewers will probably not be upset. Your paper must be judged by your results at the time of submission, but if it is provisionally accepted, you will be able to replace results with your new results in the final publication version, subject to approval by the senior reviewers.

Anonymity

How do I include a reference to myself without identifying myself?
The general rule is to use the third person. For example, if Fred Brooks were to write a paper, he might say in his "related work" section: "Brooks et al. [12] discuss a system in which molecular visualizations are ... Our work builds on some of the ideas presented there, and on the ideas of Smith et al. [14] and the interaction techniques described by Wolford [18]." He would NOT say: "The authors, in prior work [12], discussed a system in which molecular visualization ... " The only case in which anonymous references are appropriate are unpublished manuscripts, in which case he might write: "The authors have also developed closely related techniques for molecular manipulation [15], but that work is outside the scope of this paper." Reference 15 would then read: [15] Anonymous Authors. Molecular manipulations through computer graphics, submitted to CACM.

If there is any danger that reference [15] might be considered a dual submission, then you should submit it as supplemental material with your SIGGRAPH Asia 2009 submission, along with a cover letter (also submitted as supplemental material) briefly explaining the differences between it and your SIGGRAPH Asia 2009 submission. You do not need to anonymize the cover letter, and you do not necessarily need to anonymize the supplemental manuscript either. However, if you believe it is important that all reviewers see that manuscript (for example, because it explains background concepts they might need in order to judge your SIGGRAPH Asia submission), then send in an anonymous version with your SIGGRAPH Asia 2009 submission. This will allow it to be sent to tertiary reviewers. Be aware that even if you do not think the reference is important to the reviewers, some reviewers may want to see it, necessitating complicated efforts by the SIGGRAPH Asia 2009 reviewers to help them obtain it anonymously. So please consider uploading anonymous versions of any anonymous references.

Please submit these supplementary materials (and any cover letter) electronically. The submission form provides separate areas for submitting supplementary materials intended to go to all reviewers versus supplementary materials intended to go only to the primary and secondary reviewer. Non-anonymized materials that would identify you as the author, including any cover letter, should go in the second area.

My SIGGRAPH Asia submission needs to cite a tech report or thesis that might be hard for reviewers to find. What should I do?
You are encouraged to submit that report or thesis as supplemental material. Cite it in the third person in your SIGGRAPH Asia 2009 submission, even if you are one of its authors. This avoids the necessity of anonymizing it.

My SIGGRAPH Asia submission needs to cite one of our own web pages, which can't easily be anonymized. Now what should I do?
If you can reasonably cite the web page in the third person, go ahead. Remember, however, that reviewers may be reluctant to visit cited web pages, since doing so could compromise their anonymity. If for some reason you can't cite a web page in the third person, or if doing so would compromise your anonymity (for example, the same pictures appear in your submission and on the web page, or the web page includes a link to a paper by you that is cited in your SIGGRAPH Asia 2009 submission as Anonymous Authors), then don't cite it; find another solution. If in this unusual case you're worried about a reviewer thinking that you've appropriated other people's work without proper citation, then submit as supplemental material a letter explaining the situation. You do not need to anonymize this letter. Of course, you can also upload as supplementary material your web page .html source, and any other files it points to.

My SIGGRAPH Asia 2009 submission needs to cite another, concurrent SIGGRAPH Asia 2009 submission by our group. Now what should I do?
Cite it as [16] Anonymous Authors, A grand unified theory of computer graphics, submitted to SIGGRAPH Asia 2009, and submit as supplemental material a letter telling us which paper_id you are referring to. As described above, it is a good idea to upload this anonymous reference as supplementary material, in case reviewers want to see it.

I know I am supposed to remove my name, company name, etc. from the document, but should I also remove names from the acknowledgments? If the paper is accepted, should I send another copy to you with this additional material?
You should not include an "acknowledgments" section in the submission. If your paper is accepted, you will submit a revised version that identifies you and your co-authors, your affiliations, and any acknowledgments that are appropriate (so consider the extra space that this will require when stating how may pages the paper will occupy).

Other Questions About Submissions

Where can I find a list of the Computing Reviews categories? Also, are we restricted to using keywords specified on the web site?
Yes, select one Computing Reviews primary topic area and one or more secondary topic areas that best describe your paper. These topic areas will help the paper sorters select appropriate senior reviewers for your paper. See ACM's Computing Classification System to determine the selection of keywords to describe your paper.

The Publication Requirements page says pages should be numbered, but the document preparation instructions say that page numbers should not be included. Which is correct?
You should number the pages. For the final version, if your paper is accepted, we'll ask that you not number the pages, but please number them for the submission. The sample documents in Document Preparation for Conference Proceedings all include page numbering.

I have video material I need to submit. May I submit it on a VHS tape or DVD-ROM?
The recommended procedure is to upload as supplementary material animations and videos in digital video files that can be easily downloaded and viewed by reviewers, rather than in physical media that are harder to handle and distribute. If you believe that the higher quality or resolution, or larger file size, allowed by a physical medium is necessary to evaluate your paper, you may use the shipping process described in the next question below.

I have a hologram, a cloth sample, a page printed with non-standard inks, an auto-stereogram, or some other physical material that I need the reviewers to see, that I cannot supply electronically. What should I do?
You may mail or ship six copies of such supplementary materials to the papers chair:

Even if you ship physical versions of your paper itself, you must still upload a PDF version to the online submission system. In order to be considered for reviewing, all such supplementary material must arrive by the 12 May deadline. If your shipped material does not arrive by 12 May, and you upload a PDF paper by then, your submitted paper will be reviewed without the shipped material.

The details in my imagery are very subtle: I am concerned that the reviewers will not print my paper on a suitable printer or view my video with an appropriate codec.
You still need to submit your paper as a PDF file. Please be aware that the reader of your final version, if accepted, may have the same problem, and plan your figures accordingly. In particular, make sure line weights on diagrams and text labels and axis numbering on graphs have not been reduced to an illegible size. (Colored lines and text will suffer more in this regard than black and white.) For images, you are encouraged to include enlargements of selected sections to show details. You may include larger images in supplementary materials, and/or add in your submitted PDF paper a note to reviewers to look at enlarged versions of certain figures on their monitors, but this is not appropriate for the final version, so please prepare a paper that can be appreciated in print. You may also ship physical versions of the paper or of selected images, as described in the previous answer, but this is not encouraged for material that will be printed in the proceedings with the normal printing process. You may also ship your video on physical media if necessary.

Does the video submitted by 12 May have to be final quality? Or will people whose papers are accepted have the opportunity to prepare a more polished video?
You'll have the opportunity to prepare a more polished video. Of course, the better the submitted video looks, the more likely reviewers will be able to see the strength of your work, so early polishing is a good investment of time and energy. (But note the five-minute duration limit and 100 MB total file size limitations for supplementary material in the Publication Requirements). If your paper is accepted, you must submit your video or its revised version via the final upload page in the online submssion system, for inclusion in the conference DVD-ROM and the ACM Digital Library. Any such submitted videos will also be considered for inclusion in a Papers Preview section of the Electronic Theater program. If a specific section of your video is selected, you will be encouraged to produce a 1080p version of that section for this purpose, but if you do not, whatever version you have uploaded will be used.

Do we have to prepare the paper in the final format?
Yes, please do so. Seeing a paper in final format lets us verify the page count and allows us to compare it to other papers.

What is the page limit for papers?
There is no arbitrary maximum length imposed on papers. Rather, reviewers will be instructed to weigh the contribution of a paper relative to its length. Typical research papers are eight pages long. However, in any given year, it is common for papers to be accepted with as few as four pages and as many as 12 pages. See Publication Requirements for more details.

My submission is a revision of a paper I submitted to an earlier SIGGRAPH conference. Will the reviewers get to see the earlier reviews?
Not unless you authorize them to. There are two ways you can do this. You can submit the previous reviews yourself, by uploading them as supplementary material. In this case, it is a good idea to upload the previous submission also, so the reviews and your revisions in response to them can be placed in context. You may also identify the previous paper on the submission form, and authorize that the (anonymized) reviews, the previously submitted materials, and the BBS discussions, be transmitted to reviewers from the submission database for your previous submission. In addition, you may also authorize that the previous reviewers' names be transmitted to the paper sorters and the senior
reviewers of your new submission. In this case, there is a good chance that the previous reviewers can be reassigned to your paper. See the Publication Requirements page for more details.

Hey, I know your REAL email address. Can I use that?
No, use the Papers Email Contact Form. Why? First, I might be unavailable for several days. Second, during parts of the submission and review process, I will be buried in email. If you use the contact form, your email will go to the Papers Chair and selected administrators. One of them may be able to answer your question, and they will often do so surprisingly promptly.

If you have a question of extreme delicacy, or a question on which the Papers Chair or a member of the Papers Advisory Board might be conflicted, please contact the Technical Papers administrative support team via the contact form. Neither the Technical Papers Chair nor reviewers will receive such emails.

Deadlines

Can I submit after the deadline?
No. The deadline is absolute.

But I had a major life event (birth, death, divorce ...) just two days ago!
The deadline is absolute. You may, of course, submit the work in its current form by the deadline, even if it's not the paper that you'd like it to be.

But my fancy color printer stopped working at 4 pm, and the FedEx deadline is looming!
The deadline is absolute. Equipment failures are common, and SIGGRAPH Asia 2009 cannot adapt its schedule to accommodate them. If you upload a PDF file by the deadline, your paper will be considered without the specially printed supplementary material you had hoped to ship.

I was unable to upload my submission on time. The system was overloaded, and halfway through uploading my submission the deadline passed.
The deadline is absolute. Submissions that are in progress when the 13 May delayed deadline passes, even if it's because our server has slowed down due to high load, will not be accepted. You should allow enough lead time to avoid this kind of problem. Please see the Detailed Instructions for explanations of the MD5 checksum process, and the meaning of the 12 May deadline and the 13 May delayed deadline.

Unfortunately, in our rush to meet the deadline, we incorrectly set our gamma during taping, so we sent a fairly poor-quality video. I have since corrected the problem. May I substitute new videos for the ones I submitted? The video is identical, except for the gamma correction.
No. The submission deadline is absolute. All materials must be submitted by the deadline. If your paper is accepted, you will have the opportunity to replace the video.

I'm using the SIGGRAPH Asia 2009 English Review Service, and they didn't get back to me soon enough, so it's SIGGRAPH Asia 2009's fault that my paper isn't ready. Can I submit late?
The deadline is absolute. The English Review Service makes no guarantees about turnaround, and it's up to you to make contingency plans.

I'm not in the US, and US Customs often holds up submissions, so I have to send my physical supplemental materials off two weeks earlier than US researchers would. Can I send it by the deadline instead, and you'll receive it about two weeks late, after US Customs has had a chance to process it?
The deadline is absolute. If your supplemental materials must pass through various hurdles to get here, you must plan in advance how to submit it early enough to ensure arrival on time. If the PDF file is uploaded by the deadline, we will review your paper without any shipped material that arrived late.

I gave my supplemental materials to Federal Express, and I have a receipt to prove that they promised delivery before the deadline, but there was a snowstorm in Sacramento, and Federal Express couldn't meet their promise.
If you can provide the receipt (and we'll ask for it), then we'll accept the materials whenever Federal Express delivers them, but cannot guarantee that they will reach reviewers in time to influence their reviews.

Why is the SIGGRAPH Asia 2009 submission deadline so much earlier than it was for SIGGRAPH Asia 2008, even though the conference will be later?
The deadline is earlier for several reasons. In an effort to control travel time and expense for the SIGGRAPH Asia 2009 Papers Committee meeting, that meeting is held the weekend before the summer SIGGRAPH conference, and that conference is a week earlier this year. There is also an added week in the review process, just before the Papers Committee meeting, for extra reviews of papers for which the originally selected reviewers cannot come to a consensus recommendation for acceptance or rejection. In the past, such extra reviews were done during the meeting itself, which placed a burden on the extra reviewers, and did not allow them time to do the best possible reviewing job. The deadline is on a Tuesday rather than a Wednesday, to allow an extra day of preparation for the papers sort (see Review Process). The earlier Papers committee meeting, by its effect on the rest of the deadlines, will allow the proceedings to be published and shipped two weeks before the conference, so that Transactions on Graphics subscribers can bring them to the conference.

Review Process

I am submitting a paper on topic X, which I know is an area of expertise for committee member Y. Can I ask that Y be a senior reviewer of my paper?
No.

I am submitting a paper on topic X, which I know is an area of expertise for committee member Y. Can I ask that Y not be a senior reviewer of my paper, because Y works for a competing company?
No. Indeed, Y may well be the best qualified reviewer for your work, and if so, we may ask Y to be the senior reviewer. Reviewers will be instructed that information in unpublished submissions is confidential, to be used only for the review process.

Am I allowed to ask for my paper to not be reviewed by someone from whom I do not expect a fair review?
No. The reviewer selection process includes no such provisions. Occasionally during the committee meeting there is discussion such as: "This paper got scores of 5, 4, 5, 4.5, and 2, but let me explain the score of 2. The reviewer picked at small details, was angry that his own work had not been properly cited (although when I looked at it, it appeared to have been treated more than fairly), and then wrote a very cursory review of the main contribution of the paper. It seems as if there's something going on here that doesn't have to do with the quality of the paper, and we should discount this score as an outlier."

Isn't the committee more likely to accept papers by committee members and other insiders? How do you prevent a conflict of interest?
Any paper on which a committee member has a conflict of interest will not be discussed while that committee member is in the room. While each committee member has a list of papers and the committee members who reviewed them, these lists are customized so that the names of the members who reviewed papers on which I have a conflict of interest will not be shown on my list. In general, the acceptance rate for papers by committee members has been slightly higher than the acceptance rate for those in the overall submission pool. But the acceptance rate for these same people has also been higher in years when they were not on the committee; they're invited to be on the committee, in part, because of their expertise in the field.

I'm a Technical Papers reviewer, and I'd like to show this paper to one of my students, who frankly knows more about the topic of this paper than I do. May I?
Yes. You may show a paper under review to a small number of people, normally one or two, providing that you:

1. List their name(s), title(s) (for example, "my PhD student"), and affiliation(s) in the private section of the review form, which goes only to the papers committee.

2. Clearly instruct them on the rules of confidentiality of the SIGGRAPH review process.

However, it is not appropriate for others to write the review for you. If this is your intention, then you must discuss it with the senior reviewer who assigned you the paper. At their discretion, they may officially reassign the paper to your student. In this case, you lose a free mug, and the student gains one!

Rebuttal Process

Reviewer #4 clearly didn't read my paper carefully enough. Either that or this reviewer doesn't know anything about the field! How should I respond during the rebuttal period?
We've all received SIGGRAPH reviews that made us mad, particularly on first reading. The rebuttal period is short and doesn't allow for the cooling-off period that authors have before they write a response to a journal review. As a result, authors need to be particularly careful to address only factual errors or reviewer questions in the rebuttals rather than letting their emotions show through.

Please don't say: "If reviewer #4 had just taken the time to read my paper carefully, she would have realized that our algorithm was rotation invariant."
Instead say: "Unfortunately, Section 4 must not have been as clear as we had hoped because Reviewer #4 didn't understand that our algorithm was rotation invariant and he was therefore skeptical about the general applicability of our approach. Here is a revised version of the second paragraph in Section 4, which should clear up this confusion."

Remember that your rebuttal gets sent to all the reviewers; you don't want to offend them. In particular, you want the two senior reviewers to come out of the rebuttal process sufficiently enthused about your paper to champion it at the committee meeting, and if the paper is accepted and needs revision, then you want them to feel sufficiently comfortable with you as an author that they are willing to "shepherd" the paper through the revision process.

Now that I've read the reviews of my paper, I see much better how to organize it so it will be clear to the reader. Can I do this reorganization and upload the new version during the rebuttal period?
No. The rebuttal period is for addressing factual errors in the reviews, not for getting revised text into the review process. The committee members will have only a short time in which to read and act on your rebuttal, and it must be short and to the point. Hence, it will be limited to 2,000 words. You will have the opportunity to reorganize it for publication if it is accepted.

Between May and late July, we've gotten some really cool new results for our paper. Can I upload those results during the rebuttal period? I'm sure that they will make the reviewers realize the importance of our approach.
No. The rebuttal period is for addressing factual errors in the reviews, not for getting new results into the review process.

Reviewer #2 says that our collision-detection algorithm won't work on concave objects. But it will, as we just demonstrated with the lid of the teapot. Can we upload a movie showing this new result?
No. Time is very precious at this stage in the review process, and you must keep your rebuttal short, or the reviewers and committee members will not have time to read it. No supplementary material may be uploaded during the rebuttal period, only 2,000 words of text.

Why can't we upload images and videos as was possible last year?
Over the past few years, authors could ask the committee for permission to post images, audio, and/or videos on the public BBS. While this feature was sometimes helpful for providing examples that answer specific questions posed by referees, it was used very differently by different authors and regulated differently by different referees. In some cases, an author would be allowed to upload entirely new examples, while nothing was allowed in others. The instructions clearly stated that rebuttals are only for "addressing factual errors in reviews". Yet, some authors would push the limits (for example, "the review said my method doesn't work, and so here are several new results to show that it does work ..."), and some referees were more lenient than others in allowing such uploads. To improve the uniformity of the review process, rebuttals will be limited only to 2,000 words of text. No images and no video can be uploaded with the rebuttal for any paper. This change should improve the fairness of the rebuttal process, and also decrease the pressure on submitters to create new results during the short rebuttal process.

Will we use the bulletin board system (BBS) for discussion during the rebuttal period?
There will be no discussion back-and-forth between authors and referees on the public BBS during the review process. Last year, referees could ask questions of authors on the public BBS at any time prior to the committee meeting, and authors could provide extended answers, sometimes with new visual results in response to specific questions. Thus, the review process was different for different papers, and unnecessarily stressful for all. This year, posts by referees to the public BBS will be disabled during the rebuttal process, and thus the public BBS will be used only by authors to upload a single, text-only rebuttal. This change should increase the fairness and reduce the stress of the rebuttal process. If you paper is accepted, the bulletin boards will be opened for discussions during the revision process.

I answered all reviewer criticisms during the rebuttal period, but no one responded, and now my paper is rejected. How can I be sure the reviewers received and actually read my rebuttal?
The reviewers and committee members will have only a short time in which to read and act on your rebuttal. You will not receive a response to your rebuttal. If you can view your rebuttal comments in the online review system, so can your reviewers. Rest assured that rebuttal information is considered and can be very helpful in the selection process.

Presentations

Are papers merely published in print, or is there a presentation as well?
There is a presentation, of about 20 minutes length, followed by five minutes of discussion and questions. One of the authors of the paper must commit to making this presentation, in Yokohama at SIGGRAPH Asia 2009, for the paper to be accepted. Also, in addition to the print format, the paper will be available in electronic format in the ACM Digital Library and as part of the conference DVD-ROM.

Where can I get the ACM Copyright Form on the web? I need to show it to my employers before I submit.ACM Copyright Form (PDF)

My paper was just accepted to SIGGRAPH Asia 2009, and I'm thrilled. But now my boss points out that I can't use Mickey Mouse as the example in my paper because I don't have the rights to use him. What do I do now?
The Permissions and Copyrights section of the Publication Requirements page explicitly states that you must have permissions for all the images in your paper and the footage on your videotape, CD-ROM, or DVD-ROM at the time of submission. You should immediately tell the Papers Chair what you propose to use as a replacement. If the new images or footage are not substantively similar to that submitted for review in the judgment of the Chair and the Papers Advisory Board, then acceptance of your paper will be rescinded. The archival record (Proceedings, DVD-ROM, and ACM Digital Library) must contain material that is equivalent to what the reviewers saw at the time of review.

Getting a Paper Accepted

What follows is not "official" SIGGRAPH policy, but rather the idiosyncratic impressions of former Papers Chairs, based on many years of service on the Papers Committee.

Is it important to submit a video with my paper?
There is a very strong correlation between submitting a video and getting accepted. An animation paper without a video is almost certain to be rejected.

Why are good papers rejected?
Check out this article by Jim Kajiya, the Papers Chair for SIGGRAPH 93, for many excellent reasons. Although some of the details are dated, the general wisdom is timeless.

My paper was recommended for consideration with major revisions in a subsequent issue of ACM Transactions on Graphics. Does it have to appear there or can I submit it somewhere else?
SIGGRAPH Asia 2009 submissions can be withdrawn at any time. The offer to publish a revised version of the paper in an upcoming TOG issue is completely at the discretion of the author.

How do I decide whether to submit my work as a paper, a sketch, or a poster?
The Technical Papers program is the most competitive of these three. Technical Papers also give you a chance to work out your ideas at greater length. Finally, Technical Papers represent a citable archive, which are stored in the ACM Digital Library and elsewhere; beginning in 2008, SIGGRAPH and SIGGRAPH Asia Sketches and Posters will not appear in the ACM Digital Library, and are therefore not citable as prior work by other papers. Sketches and Posters have a later submission date, 17 August 2009, allowing you to submit more recent work than the Papers Program does. If you believe your work is sufficiently mature to be a paper, then submit it to the Technical Papers program.

How soon will my paper accepted with major revisions be published in ACM Transactions on Graphics?
The revisions will be verified by the original SIGGRAPH Asia 2009 reviewers, which greatly accelerates the refereeing process. If the revisions are made in a couple months and found acceptable, the paper would likely appear in the April or October issue, which may give you the opportunity of presenting the paper at SIGGRAPH Asia 2010.

My paper was accepted with major revisions to ACM Transactions on Graphics. Great, but I want to submit it to another workshop, symposium, or conference first.
The offer to retain the original SIGGRAPH Asia 2009 reviewers evaporates the moment the paper is submitted anywhere else. The paper can always be submitted to TOG later, but it will be reviewed through the ordinary refereeing process, which may, but probably will not, include any of the original SIGGRAPH Asia 2009 reviewers.

Patents and Confidentiality

What about patents and confidentiality? Are the two senior reviewers and the three tertiary reviewers under a confidentiality agreement not to disclose the contents of the paper to others? Some organizations like IEEE have all reviewers sign a confidentiality agreement. It's very important that I know for sure, since my employer may want to apply for a patent, and it affects when I may submit the paper to the SIGGRAPH Asia conference. Can I, for example, get a written guarantee of confidentiality?
Reviewers are asked to keep confidential all materials sent to them for review, but they do not sign a confidentiality agreement. In general, there is wide respect for the confidentiality of submissions, but we cannot promise anything, or provide a written guarantee.

It would not be wise for SIGGRAPH to give you legal counsel on the matter of patents and publication; we urge you to seek independent legal advice. The main issue is that in different jurisdictions (such as Europe) prior public disclosure could invalidate a patent application. The situation is different in North America, where you have one year after public disclosure (for example, publication) to file a patent. It is a common practice for authors to prepare a patent filing coincidentally with their SIGGRAPH publication. The publication date of the SIGGRAPH Asia 2009 proceedings issue of ACM Transactions on Graphics will be 2 December 2009. Note that this is a week earlier than the former date of one week before the conference. (See the last question in the Deadlines section above.)

When will my paper be publicly available?
Technical Papers accepted for presentation at SIGGRAPH Asia 2009 will be published in ACM Transactions on Graphics 28(5), a special fifth issue available in print and electronic format, on 2 December 2009. Brief descriptions of accepted papers will be published on the SIGGRAPH Asia 2009 web site in September 2009.

Volunteering for the Technical Papers Program

I've been doing graphics for years. May I be on the Technical Papers Committee?
The Technical Papers Chair selects the committee. I (Nelson Max, SIGGRAPH Asia Technical Papers Chair) have selected an initial committee with several goals in mind, including: coverage of areas in which I anticipate submissions, getting some "old hands" who have been on the committee before, bringing some new folks into the process, with special consideration to those who have volunteered, recruiting people who will work well together and treat papers with respect and enthusiasm, and getting representation from diverse communities. If you'd like to participate, send email soon to the Technical Papers Chair and tell me about yourself and your areas of expertise. I may still need you at the last minute, if more papers are submitted in your research area than I anticipated when first chosing the committee.

I've volunteered to be on the committee for three years now, and I've never been chosen. What's up with that?
It may be that others are better qualified, that we already have committee members with expertise in your area, that the chairs do not feel that you've been in the field long enough to be an effective committee member, or any number of other reasons. The committee composition does change from year to year, though. Please keep offering your services.

Just what sort of workload is involved in being on the Technical Papers Committee?
You must review about 20 papers by the 10 July deadline. For about 10 papers, you must find two additional reviewers, and for the remaining papers you must find one additional reviewer. You must attend a Technical Papers Committee meeting in New Orleans on 1 and 2 August 2009 (the weekend at the beginning of SIGGRAPH 2009), during which time you'll discuss papers, possibly be called on to provide additional reviews of a couple of papers, and be expected to listen carefully to a lot of discussion that has little to do with you. Starting on 20 July, you must work with the other senior reviewers to come to consensus recommendation for acceptance or rejection. If this consensus is not possible, the paper will be tabled, and you will need to select one or more other members of the Technical Papers Committee to review it. Thus you yourself may be asked to write a few extra reviews during the week before the meeting. You may also be asked to act as a referee for a paper that's been conditionally accepted, to verify that the final version meets the requirements set for it. For papers that are not accepted for the conference, but recommended for ACM Transactions on Graphics, you may be asked to remain as a reviewer during the TOG review process. Finally, you may be asked to chair a Technical Papers session at SIGGRAPH Asia 2009. See the Review Process page for more details.

What do I get for all the work that I'll be doing as a committee member?
In material terms, you get a 50% discount when registering for SIGGRAPH Asia 2009 and SIGGRAPH 2009, and you'll probably receive a t-shirt as well. You also receive the recognition of your colleagues, the gratitude of authors, and the sense of satisfaction that comes from knowing you've given something back to the organization that helps disseminate research in graphics.
